What is the difference between kraft liner and testliner?
Linerboard made of virgin pulp is called kraftliner, whereas recycled linerboard is known as testliner. The corrugating medium may be recycled medium, called wellenstoff in Europe, or virgin, which is called semichemical medium for the type of pulp used in its production.
What is testliner paper?
TESTLINER Paper is intended for industrial cardboard packaging manufacturers. The Testliner is mainly used as a cover layer of corrugated cardboard, and made from 100% recycled fibers.
What is fluting in paper?
Fluting paper is the middle liner of corrugated board, which can be used individually as a type of protective packaging paper. We offer Fluting/Medium in 90-300gsm range. Fluting provides protection by filling empty spaces in the outer case, providing a cushioning support for the primary product.
What is kraftliner used for?
Kraftliner is used in production of economical, lightweight packaging material called flat corrugated fiberboard. This material has high wear resistance and rigidity performance, does not cave in – a great option for production of packaging.
Is B flute or C flute stronger?
C Flute. Between 3.5mm and 4mm in thickness, C flute offers greater compression strength than B Flute. This means it provides better stacking strength when used for lightweight products.
How many types of Kraft paper are there?
Kraft paper is produced by a sulfate treatment process. Kraft paper is available in several forms either as natural brown, unbleached, heavy duty, or bleached white. The natural kraft is the strongest of all paper and is commonly used for bags and wrapping.
What is white top testliner?
White Top Testliner is a 2-ply paper. The top side is either produced of fresh fibres or recycled fibres (bleached), the bottom side (brown or grey) consists of waste paper for 100 percent. The coated top side of this improved quality provides a smother and brighter surface for better appearance and printing results.
What is fluting in printing?
Fluting is a condition which is produced in the printing process and defined as a series of waves or corrugations which run in paper-grain and web-travel direction. The problem is exclusive to web heatset printing with objectionable intensities of fluting being most evident on lightweight papers.

What is the strongest flute?
A-Flute. A-flute is the original corrugated flute design and is the thickest. With it’s thickness , A-flute provides the greatest cushioning properties for fragile products. Because A-flute offers excellent stiffness qualities and short column crush resistance, it has application across a broad range of customer uses.
Is E flute stronger than F-flute?
F-flute is about half as thick and E-flute and has about 35 percent more flutes per inch (128 for ‘F’ vs 95 for ‘E’).
What is coated kraft paper?
The kraft paper can be of various strength and finish as per the requirement. The paper if polycoated will give it more strength and also the moisture barrier property. The paper can have sandwich layers if more strength is required.
Can kraft paper be white?

Is C flute better than B flute?
With a thickness of 1/8″ and shorter flutes, this type of box still provides a rigid, flat surface for printing. C-flute is commonly used for shippers. The flutes are taller here at 3/16″, giving C-flute somewhat better cushioning properties than B-flute.
What is stronger B flute or E flute?
B flute (2.5-3.5mm) is the most common flute profile for shipping boxes. As it’s thicker than E flute, it offers more cushioning and better puncture resistance, but it still has a smooth surface for printing on.
Which is stronger B or C flute?
Is kraft paper better than white paper?
Bleached kraft paper is the strongest white paper. It is used where strength, printability, and appearance are important, such as flour and sugar bags, labels, and envelopes. Bleached kraft fibers are also used in production of solid bleached sulfate (SBS), a high quality paperboard (Soroka, 2002).
What’s the difference between butcher paper and kraft paper?
What makes butcher paper different from kraft paper comes down to the treatment applied to butcher paper to strengthen it for food grade use. Butcher paper is engineered to withstand moisture better than kraft paper and offers superior blood, and moisture holdout than standard kraft paper.
